Wie ein Inhalt eines Dokuments in Elasticsearch Index

Question

an suche ich den Index in Elasticsearch als

this.client.CreateIndex("documents", c => c.Mappings(mp => mp.Map<DocUpload> 
       (m => m.Properties(ps => ps.Attachment 
            (a => a.Name(o => o.Document) 
              .TitleField(t => t.Name(x => x.Title).TermVector(TermVectorOption.WithPositionsOffsets)) 
              ))))); 

die Anlage erstellt haben, ist base64 vor der Indizierung codiert. Ich kann keinen Inhalt in einem Dokument durchsuchen. Ist die base64-Codierung ein Problem? Kann mir bitte jemand helfen?

Browser Antwort ist wie

Answer 1

ich die Lösung durch Zugabe eines Analysators gefunden.

var fullNameFilters = new List<string> { "lowercase", "snowball" }; 
     client.CreateIndex("mydocs", c => c 
       .Settings(st => st 
         .Analysis(anl => anl 
         .Analyzers(h => h 
          .Custom("full", ff => ff 
           .Filters(fullNameFilters) 
           .Tokenizer("standard")) 
          ) 
          .TokenFilters(ba => ba 
           .Snowball("snowball", sn => sn 
            .Language(SnowballLanguage.English)))      
          )) 
         .Mappings(mp => mp 
         .Map<IndexDocument>(ms => ms 
         .AutoMap() 
         .Properties(ps => ps 
          .Nested<Attachment>(n => n 
           .Name(sc => sc.File) 
          .AutoMap() 
          )) 
         .Properties(at => at 
         .Attachment(a => a.Name(o => o.File) 
         .FileField(fl=>fl.Analyzer("full")) 
         .TitleField(t => t.Name(x => x.Title) 
         .Analyzer("full") 
         .TermVector(TermVectorOption.WithPositionsOffsets) 
         ))) 

         ))       
         );
